## Overview

MARK•R is a browser plugin built around one interaction: highlight text, then talk to it. Instead of copying a passage into a separate chatbot, you select it on the page and a small icon appears with an AI input field. Whatever you ask is answered inline, in the flow of reading, which keeps the source material and the conversation in the same visual context.

The distinguishing design decision is that MARK•R does not restrict itself to the highlighted fragment. It reads the surrounding page as well, so questions can be about the wider argument, the definitions used elsewhere in the article, or the assumptions behind a claim. That makes it more useful for interpretation and analysis than a simple selected-text rewriter, and it is the reason the plugin is marketed for research, study and content development rather than only for editing.

Practical applications cluster around comprehension and production. Students and researchers use it to unpack difficult concepts and terminology; professionals use it to clarify technical, legal or medical language; writers and marketers use it to generate summaries, outlines and alternative phrasing; and anyone drafting email in a browser can highlight the message they received and ask for suggested replies. Access is tiered: a free plan with a modest daily allowance of GPT-3.5 calls, paid Standard and Pro plans that add higher limits and GPT-4, and custom builds for organisations. The published plan structure references GPT-3.5 and GPT-4, so newer model options may not be available on this tool.

## Pricing & Plans

Freemium. A free tier provides 15 calls per day, 2,000 highlighted characters, 500 characters of prompt input, GPT-3.5 and 1,000 output characters. Standard is $8 per month and Pro is $12 per month, adding higher daily call limits, larger character allowances, longer output and GPT-4 access (one GPT-4 call equals 20 GPT-3.5 calls). Custom builds are available for organisations and enterprises.

## Key Features & Capabilities

- **Highlight-to-ask interaction:** Selecting any passage on a page activates a dynamic icon and AI prompt field, so a question can be asked at the exact place you are reading rather than in a separate chat window.
- **Whole-page context:** Responses draw on the surrounding article or page, not just the highlighted fragment, which supports deeper questions about argument, terminology and implications.
- **Inline content generation:** Ask for an executive summary, a white-paper outline, slide talking points, suggested email replies or rewritten copy without leaving the browser.
- **Comprehension support:** Explain difficult terms, unpack technical or legal jargon and request simpler phrasing, which helps with dense academic, medical and financial material.
- **Tiered daily allowances:** Free, Standard and Pro plans set different daily call limits, character allowances, output lengths and model access, with custom enterprise builds available.

## Primary Use Cases

- **Decode dense papers while reading (Student or researcher):** Highlight a difficult paragraph in a journal article or study and ask for a plainer explanation, a definition of the terminology, or the assumptions behind the claim.
- **Clarify technical and legal language (Analyst or professional):** Highlight contracts, standards, industry reports or financial disclosures and query acronyms and specialist concepts without leaving the source document.
- **Turn research into drafts (Writer or marketer):** Request an executive summary, a white-paper outline or slide talking points from material you are reading, then iterate on the phrasing directly where you found it.
- **Draft replies from the message itself (Browser email user):** Highlight an incoming email or marketplace message in your browser and ask MARK•R to suggest responses before you start typing.

## Strengths

- Works inline on any page, so you never have to copy text into another tool
- Uses the whole page as context, not just the highlighted passage
- Low entry price with a genuinely usable free tier and clear plan differences
- Broad range of applications from study and research to summaries and email replies
